United States Patent WOVEN ELASTIC WEB John V. Moore, Pawtucket, R. I., assignor, by mesne assignments, to Moore Fabrics, Inc., Pawtucket, R. L, a corporation of Rhode Island Application August 23, 1952, Serial No. 305,953

1 Claim. (Cl. 139-423) This invention relates to a Woven elastic web of improved and novel construction.

In its preferred form, my improved web is of two-ply construction, with the two fabric layers united at their edges and also at spaced points in the body of the web. Such a web possesses important advantages which will be hereinafter set forth.

My invention further relates to arrangements and combinations of parts which will be hereinatfer described and more particularly pointed out in the appended claim.

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a plan view of a portion of the improved web;

Fig. 2 is a transverse sectional view thereof; and

Fig. 3 shows the weave in draft form.

Referring to the drawings, my improved web comprises a woven upper body layer 10, a woven lower body layer 11, and selvage portions 12. The filling or Weft F is commonly nonelastic and may be cotton, sill:v or rayon.

The warp threads are commonly all elastic and may comprise selvage threads 20, 21, 22 and 23 at each edge, body warp threads 25 and spot or binder warp threads 30 and 31.

The selvage threads are preferably woven l-up and 1- down alternately, but with the threads 20 and 21 together.

The selvage construction is not claimed herein but relates to the subject matter of prior Patents No.

2,418,187 and No. 2,557,315, belonging to the same assignee.

The body portion is two-ply and the warp threads 25 in each ply are shown as woven l-up and 3-down, and 3-up and l-down alternately, this combination being repeated a desired number of times.

I then form binder spots by inserting warps 30 and 31 which are held down under both layers for a double pick at spaced intervals and which thereby bind the upper and lower plys or fabric layers together. Between the binder spots, the threads 30 and 31 may be woven 3 and 1, the same as the body warps.

By this construction, I provide a two-ply woven elastic web which presents a desired fine surface, and I avoid puckering of the fabric when in use. Furthermore, the spaced spots do not in any way restrict the desired lengthwise elasticity of the fabric and are substantially spaced apart, both warp-wise and weft-Wise thereof.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:

A woven elastic web comprising upper and lower body plies and single ply selvage portions, and said web having elastic warp threads, and certain of said elastic warp threads being normally woven in one of said plies only but being passed through the other ply and back and connecting said two plies together for two picks only at points which are substantially spaced apart both warp-wise and weft-wise, and certain other of said elastic warps being woven in the other of said plies only, and said upper and lower plies being otherwise free of each other except at the selvage edges.
